This week, we're updating our course layouts and descriptions. Presentation and materials always gently change over time, but just occasionally there's a need to make a step change to clear out some of the old and roll in the new. That's now happening - but over a long and complex site it's not instant and you'll see sections of the site changing up to and including 19th September.

grep for lines between words in a file

Posted by ramkriz (ramkriz), 26 August 2008
Hi all,

I have a file called as sample. I need to grep all the lines present between
the keywords "start" and "End" in the file. I started with this but it never enters the IF loop.  Any help to grep the data from the file will be helpfull.. Do let me know if there is an easier approach than this..

Code:
set file sample
set Intial start
set test 1
set Final end
set found 1
set fp [open $file ]
while {-1 != [gets $fp line]} {
if($test)
 {
 set test  [string compare $line $Initial]
 set found =1
  }
if($found)
   {
    send  "$line\r"
 
    }
}

Error:
./log
invalid command name "if(1)"
   while executing
"if($test) "
   ("while" body line 2)
   invoked from within
"while {-1 != [gets $fp line]} {

Thanks

The immediate error is a syntax one - replace

if($test)  

with

if {$test}

(change round brackets ti curly braces, and add a space after the word "if".

Looks like you've been writing too much Perl!

Yes Graham. Iam used to perl. I have done the same in perl. I need to do it in TCL...looks so difficult to me.. Need your help...
set file sim18
set Initial start  
set test 1
set fp [open $file ]
while {-1 != [gets $fp line]} {
if {$test}
 {
 set test  [string compare $line $Initial]
 set found =1
  }
if {$found}
{
    send  "$line\r"
    }
}

It throws out the following error
./tyhoonlog
wrong # args: no script following "{$test}" argument
   while compiling
"if {$test} "
